RADIATOR FOR HOT-AIR FURNACES.

Specification of Letters Patent.

Patented Sept. 4, 1917.

Application filed October 30, 1916. Serial No. 128,511.

To all whom it may concern:

Be it known that I, OLIVER H. l VALLEN, a citizen of the United States of America, and resident of Marshalltown, Marshall county, Iowa, have invented a new and useful Radi ator for Hot-Air Furnaces, of which the following is a specification.

The object of this invention is to provide an improved construction for radiators for hot-air furnaces.

A further object of my invention is to provide improved means for mounting and supporting a radiator on a furnace.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- Figure 1 is a side elevation showing my device mounted as required for practical use. Fig. 2 is a vertical section of the same. Fig. 3 is an elevation of the radiator at right angles to the showing of Figs. 1 and 2. Fig. 4 is a plan of the radiator. Fig. 5 is an elevation of one member of the joint between the radiator and furnace extension.

The body of the radiator preferably is made in one piece of metal by molding and comprises a head chamber 10, a base chamber 11, side chambers 12, 13 spaced apart and affording communication between end portions of the head and base chambers, a central chamber 14 located between the 'side chambers and having a cross-section area approximately equal to the combined crosssection areas of the side chambers, which central chamber aflords communication between the head and base chambers, a joint member 15, a damper seat 16 on an inclined plane at the juncture of the central chamber 14 and head chamber 10, a collar 17 leading laterally fromthe central portion of the head chamber in registry with the joint member 15 and adapted for communication with a smoke flue 17 and a cleanout collar 19 leading laterally from the central portion of the base chamber in the vertical plane of the collar 17 These integral members may vary in size, shape and relative location but preferably are substantially as shown. The joint member 15 is arranged in an inclined plane and a hook flange 20 on the upper end thereof is adapted to engage over and with a flange 21 on a mating joint member 22 leading from a furnace. The joint member 15 preferably is formed with an endless groove 23 in its outer face adapted to be filled with sealing material such as asbestos cement, and a plane inclined marginal portion of the joint member 22 is adapted to engage said grooved face and be sealed to the joint member 15, by said cement. The inclined relation of the juncture of the joint members maintains the sealed connection between them by gravity of the radiator body, said body being hung or suspended as described. A damper 24 is mounted in the head chamber 10 and may rest at times on the seat 16 and close communication between the central chamber 14 and said head chamber. The damper is connect-ed at one end to a crank rod 25 pivoted in the body adjacent to the collar 17 and an operating rod 26, mounted for reciprocation,

is pivoted at one end to the outer end of the crank of the rod 25, whereby the damper may be moved through an are from the seat 16 to the lower surface of the top of the head chamber 10. A cap 27 is slip-jointed on the cleanout collar 19.

When the damper 24 is moved into a position adjacent to the top of the head chamber 10, as shown by dotted lines in Fig. 2, a passage is opened directly across said head chamber from the joint member 15 to the collar 17, through which smoke may pass from furnace to flue by direct draft. When desired the damper 24 is moved into the position shown by solid lines in Fig. 2 and rests on the seat 16. In such position the damper closes the passage across the head chamber 10 and'the products of combustion divide and pass laterally to and thence through the side chambers 12, 13 into the base chamber and thence through the central chamber 14 to the lower face of the damper and are directed by said damper to and through the collar 17 and smoke flue 18. Thus is draft through the radiator retarded and the products of combustion are caused to travel a sinuous course in order that heat carried thereby may be radiated through the walls of the body and be absorbed by air in a furnace casing or room to the end of heating said air.

I claim as my invention 1. A radiator, comprising a head chamber, a base chamber, side chambers communicating between end portions of the head and base chambers, a central chamber communicating between the head and base chambers between the side chambers, ingress and egress openings on opposite sides of the head chamber adjacent to the central chamber, and a damper Controlling the communication of the central and head chambers, said damper when open affording; a direct communication from said ingress to said egress opening,

and when closed causing; a divided communication from said ingress opening through said side chambers, thence through said central chamber to said egress opening;

2. A radiator comprising a head chamber having a joint member and an egress collar oppositely arranged laterally of its central portion, and also having an inclined damper seat between said point member and collar, a base chamber spaced from the head chamher, side chambers connecting end portions of the head andbase chambers, a central chamber located between the side chambers and connecting central portions of the head and base chambers through said inclined seat, a damper mounted for oscillation in said head chamber and adapted to rest on said seat at times, and. a cleanout member communicating with said base chamber.

Signed by me at Des Moines, Iowa, this sixteenth day of October, 1916.
